A nurse is caring for a client who is receiving oxygen at 2 L/min via a nasal cannula. The nurse recognizes the client is receiving which of the following inspired oxygen concentration?

A. Raise the bed to a comfortable height:
Raising the bed to a comfortable height is essential for proper body mechanics and preventing back strain. It ensures the nurse can perform the procedure efficiently and safely.

B. Stand on the left side of the bed:
While a left-handed nurse might prefer to stand on the left side for better access, this choice depends on the room layout and client position. Standing on the side where the nurse is most comfortable is essential, but it is not the primary action compared to ensuring proper bed height.

C. Raise the side rail on the working side of the bed:
Raising the side rail on the working side of the bed could obstruct the nurse's access to the client and is not generally recommended during procedures requiring close access to the client.

D. Use the non-dominant hand to insert the catheter:
The dominant hand, in this case, the left hand, should be used to insert the catheter for better control and precision. The non-dominant hand is typically used to hold the genitalia and provide stability.

A) Delayed gastric emptying: This condition refers to a slowdown in the movement of food from the stomach to the small intestine, often leading to symptoms like nausea, vomiting, bloating, and early satiety. It is not related to breath sounds and would not be detected through auscultation of the lungs.

B) Atelectasis: This condition involves the collapse or closure of lung tissue, resulting in reduced or absent gas exchange. It commonly occurs in patients who are immobile or on bedrest for extended periods, such as the client with a lacerated spleen. Decreased breath sounds in the lower lobes of the lungs are a typical finding in atelectasis, as the collapsed or partially collapsed alveoli do not allow air to move through them, leading to diminished or absent breath sounds in the affected areas.

C) An upper respiratory infection: This condition involves infections in the nose, throat, and airways and typically presents with symptoms like cough, nasal congestion, sore throat, and sometimes fever. It can affect breath sounds, but it more commonly causes wheezing, crackles, or rhonchi rather than isolated decreased breath sounds in the lower lobes.

D) Pulmonary edema: This condition is characterized by the accumulation of fluid in the lungs, often due to heart failure or acute lung injury. Auscultation findings typically include crackles or rales, particularly in the lower lung fields, but not necessarily decreased breath sounds unless there is a significant consolidation or fluid volume.
